| Abstract |
The Variational Onsager Neural Networks-based Fair proof-of-reputation consensus for blockchain with Transaction Prioritisation for Smart Cities (VONN-FPORC-TP-SC) is proposed for transaction prioritisation in smart cities. Blockchain, as a decentralised immutable ledger, has potential to boost smart city growth by ensuring transparency, data safety, dependability, efficacy, interoperability, and privacy, making it promising match for smart cities. Such instance, if existing fee-dependent or first-come-first-served processing is applied, emergency events delayed owing to competition, risking people’s lives. Here, the use of Variational Onsager Neural Networks (VONN) approach is to accomplish efficient leader election and build a Weighted Byzantine Fault Tolerance consensus algorithm mechanism in this consensus protocol. A peer-prediction-based verification technique is also presented to verify that followers ‘assessments of the leaders’ created blocks are honest. Also, because the leader will assure transaction prioritization through creating blocks, leader rotation, and the correct election method, it becomes critical for the transaction prioritization process to take place honestly and quickly on FPoR. fair proof-of-reputation consensus for blockchain. The proposed VONN-FPORC-TP-SC method is implemented on MATLAB R2019b. Then, performance of proposed method is analysed with other existing techniques. The proposed method attains 28.86%, 24.47% and 31.79% higher accuracy, 18.25%, 32.27% and 26.89% higher efficiency, and 23.21%, 17.36% and 32.35% higher robustness comparing with the existing methods such as a ML-improved blockchain consensus with transaction prioritisation for smart cities (ML-BC-TP-SC), blockchain and smart contracts to secure property transactions in smart cities (BCS-TP-SC), presented an Edge TC-a PBFT blockchain-dependent ETC system for smart cities (PBFT-ETC-TP-SC), respectively. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024. |
